A terrible creature has been plaguing the community: a man with a fishbowl for a head. When he attacks someone, the goldfish leaps out of his bowl and drinks their blood. The victim is irreversibly transformed into a goldfish! This terrible crime has happened to high-schooler Kousuke's little sister. With no other option, he takes care of his goldfish-sister as best he can.

One day, he comes across a strange girl named Ringo, who wears a school swimsuit, carries an umbrella, and keeps a gun hanging around her neck. Ringo is an apprentice blood diver, and the gun is her way of shooting herself into the wounds of the fishbowl man's victims. If she can get to them in time, she can prevent them from turning into goldfish. Ringo's mentor, Ichigo, says that she's heard of a way to turn people back from goldfish into humans. Kousuke is determined to help Ringo find a way to help his sister and the loved ones of his friends at school who have met the same fishy fate! [tethysdust]

Note: The magazine this manga was serialised in was cancelled, but the series received a continuation in Comic Earth Star.

I'm glad this continued after the magazine's unfortunate end because it's a one in a million completely weird series. I wrote a long-ish review explaining why I think so. Basically, this is a series that is definitely "action", but it's "action" that could ONLY happen in this series, utilizing mundane tools in fantastical ways to do completely strange things (capturing toxic goldfish in the chaotic and dreamlike blood/soul of a person). It only gets weirder, and the surreality is something much of the cast is aware of. Interesting.

This is really weird, but really entertaining. You can think of the two main characters as buddy cops and Goldfish Bowl Man as that one criminal they're after. My favorite part is the mindscapes they blood dive into to prevent people from being turned into goldfish. It's really different and creative.
